ROTARY VENTILATOR.

Application filed September 6, 1922. Serial No. 586,474.

To all whom t may concern:

Be it known that l, JAMES NovY, a citizen of the United States, residingat Muskogee, in the county of Muskogee and State of Oklahoma, haveinvented new and useful Improvements in Rotary Ventilatore, of which thefollowing is a specification.

This invention useful improvements in rotary ventilators, and has forits objects to provide, first, a

kcontinuously lubricated bearing for the revolving cowl, hood or head;second, to provide a bearing which is protected from all injurious gasesand temperatures; third, to provide an inexpensive and easilyreplaceable bearing; fourth, to provide as noiseless a ventilator aspossible by the use of a long guide for the supporting shaft, and onewhich is well braced and adjustable for correct alinement; and, finally,to provide a rotary ventilator which is strong and durable and designedfor long and efficient service and free from parts liable to be brokenor damaged or to easily get out of order.

The invention consists of the featuresof construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which Figure l is a centralvertical longitudinal section through a ventilator embodying myinvention. Y

Figure 2 is a top plan view of the base section thereof showing theinternal bearing means in section taken substantially on line 2 2 ofFigure 1.

Figure 3 is a sectional plan view on the plane indicated by the line 3-3of Figure 1, showing the fire-damper in closed position.

Figure 4 is' a sectional elevation of the shaft bearing housing andbearing and end of theshaft journaled therein.

In the practical embodiment of my invention, as herein disclosed, Iprovide a rotary ventilator comprising a cylindrical stationary basesection 1 and a rotary head, cowl or hood section 2, the latter beingcylindrical at its base and having its lower edge arranged to surroundand overlap the upper edge of the base section 1. These lapping edges ofthe sections 1 and 2 are reinforced by annular channel-iron braces 3.The head section 2 is provided with the usual side mouth or opening 4and has disposed therein bracing members 5 and 6. Suitably atrelates tocertain new andV tached to the head section is the vane 7 adapting saidhead section to be rotated by currents of air striking against the vane,which turns to a point of least resistance.

Secured at its upper end to the head section 2 and extending downwardlythrough the bracing members 5 and 6 is a stationary shaft 8 having atapered lower end 9 terminating in a hardened conical journal 10. Thesaid portion 9 of the shaft is received and turns within a bearinghousing 11 consisting of a six-way pipe fitting having upper and loweropenings 12 and 13 and side openings 14. The lower opening 13 is closedin a iuid tight manner by a threaded plug 15 carrying an eye 16 andformed in its upper portion with a conical cavity 17 receiving a conicalcentering point 18 on a hardened metal bearing plate or disk 19 providedwith a conical bearing recess 2O receiving the conical end journal 10 ofthe shaft 8. The lower end of the shaft thus turns in contact with adurable type of bearing which will last for a long period and which, bysimply detaching the plug 15, may be removed when worn to any extent andto admit of another bearing plate being substituted in its place.

The bearing housing 11 forms part of a combined bearing, bracing andsuspension frame structure supported by the base section 1. Thisstructure includes, in addition to said housing 11, an annular series ofsupporting and bracing arms 21 arranged at an angle of 90 to each otherand threaded at their inner ends in the openings 14 and fitted at theirouter ends in sockets 22 on the stationary base section 1. Threaded intothe top .opening 12 of the housing 11 is the lower end of an uprightsupporting tube or pipe' 23 which is connected at its upper end with` amulti-armed bracing head 24. This head 24 consists, like the housing 1l,of a six-way pipe fitting having top and bottom openings 25 and 26 andan annular series of four side openings 27. The upper end of the pipe 23is threaded into the lower opening 26 and supports the head 24 inposition. The shaft 8 extends downwardly through the head 24 and pipe 23into the housing 11, which parts form a long bearing for the lower endof the shaft, whereby said shaft is held centered in position andprevented from tilting or wobbling or getting out of proper alinement.

onnecting arms 28, which may consist of ordinary pipe elbows, arethreaded at their inner ends in the openings 27 and closed at theirouter ends by plugs 29provided with eyes 30. These eyes 30 receive thehooked upper ends orF rods 31 adjustably connected by turn buckles 32 tothe upper ends et similar rods 33 having hoolts at their lov/er endsengaging leyes 3st of plugs 35 closing the angle openings or sockets 3Goi" i iittings 37, the sleeve portions of which are itted upon the endsot the bracing arms 21. By this construction the pipe 23 and bracinghead 241- are coupled to and reinforced from the bracing arms 2l by anannular series of inclined stays which hold the said portions 23 and 24.from lateral deflection. By means or these inclined stays, which areadjustable as described, the bracing head 2d may be laterally adjustedin any direction as occasion may require to properlyv center the bracingand bearing structure and the shaft 8, whereby the shaft Will be heldfrom displacement under pressures exerted upon the head section and willmaintain said head section in proper position, the centering of theshaftadapting it to work truly in its bearing against any tendency tobind, so that at all times an easy and accurate motion of the headsec-tion is ensured.

The construction described not only provides a firm and durable supportfor the shaft and head section, but the hollowv parts of the bearing andbrace trame structure particularly parts ll, 28 and 24, provide areservoir for Oil or other lubricant, which may be introduced thereintoas required by removal ot one ot the upper plugs 29. This oil will beconiined in the bearing housing 1l, and the bearing parts ot the shaftwill thus be constantly immersed in oil, keeping them cool and reducingWear and tear to a material degree, the lii'ie oi the Working parts thusbeing materially prolonged and in addition said parts are therebyprotected from rust and disintegration from the action of the elements.For the purpose of reducing the amount of oil required, the inner endsot' the pipes 2l may be closed at the point Where they enter theopenings lil, thus confining the oil Within a reservoir portionsincluding the housing lil and more or less of the upright bearingthere-above. The shait end by being thus enclosed is at the same timeprotected from all injurious gases and temperatures and an inexpensiveand easily replaceable bearing provided therefor, which bearing andwhich structure in general ensures the production of a ventilatorlhaving a rotating part which will operate easily and in a practicallynoiseless manner the long shaft bearing and continual lubrication of thebearing surfaces proper reducing friction to a minimum. Y

Arranged Within the bottom of the stationw ary base section l is achanneled bracing ring 39, and formed at diametrically opposite sides ofsaid section l, adjacent to said ring 39, are bearing'soclrets l()receiving the ends ot a transverse rod or shaft all. To this shaft arehinged the semi-circular sections i2 of a folding re door, the sectionsof which are adapted when in closed position Y to rest upon the bracingVring 39, which forms a seat therefor. ,dit their outer peripheral edgesthe door sections lf2 are reinforced by angle airons a?) and carry'Weights de which adapt said door sections, When releas d lior closingmovenient, to drop by gravity and seat upon the bracing ring Secured tothe outer edges of the door sections are end portions or chains orcables da, which chains or cables pass in opposite direct-ions overpulleys or sheaves carried in a suspension bloclr si@ provided with ahoolr di" engaging the eye i6 oi' the plug l5, whereby said suspensionblock is supported troni traine. Vihe other ends ot the chains or cablesl5 extend downwardly through slot-s i8 in the door sections and areconnected by a fusible linlr di) with a counterbalancing Weight 50. ThisWeight 50 normally counterbalances the door closing Weights del andholds the door sections in the open position shown in Figure l, thusnormally leaving the ventilator shaft open for tree ventilation. in theevent, however, of the breaking oui ot a lire the passage oit the hotsinolre or gases through the ventilator will cause the link 4:9 to befused or melted, thus freeing the weight which will drop down and alsofreeing the chains or cables t, taus allowing the door sections 42 toimmediately drop by gravity down against the seat 39 and closing theventilator shaft.

From the lioregoing description, connection u/'ith the accon'ipa ings,the construction and inode o' o' my improved rotary ventilator readilynderstood, and the ini c .tion provi actcr which is Which is longeconomical in operation. ,also it will be seen that it provides a meanstor keeping the shaft constantly lubricated in a lengthened and bracedbearingIn which supports the shaft accurately in position and thusobviates liability ot binding oi the shaft or other derangement oi therotating parts. Furthermore it will be seen that it provides aconstruction in which the bearing parts are protected troni destructivege and temperatures, in which an easily replaceable hardened bearing isfurnished, ivl'iich may be renewed in a convenient manner Vwhen occasionrequires., which Yfurther provides for adjustment oit an eilicienttypeof bracing means whereby the bearing may at all times be kept centered,thus adapting the rovvill i. it will be seen that e i im r +1 i c@ :ttUVla, 0L iilS (hid. simple oi construct-ien and lived and he durableand the bracing and bearing 'Y tary head to operate in a practicallynoiseless manner, and which still further provides a door or damperadapted to automatically close the shaft upon the breaking out of afire. These and other advantages of the invention will be understood andreadily appreciated by those versed in the art without a further andextended description.

Having thus fully described my invention, I claim l. In a rotaryventilator, the combination of a stationary base section, a rotary headsection, a six-armed bearing housing in the base section, a six-armedbracing head enclosed within the head section above and in verticalalinement with said bearing housing, a tubular shaft guide connectingthe upper vertical arm of the bearing housing with the lower verticalarm of the bracing head, radial braces connecting the horizontal arms ofthe bearing housing with the base section at angles of 90 to each other,bracing members connecting the correspondingly arranged arms of thebracing head with said radial braces extending from the bearing housing,adjusting connections in said arms, and a shaft carried by the headsection and extending downwardly through the bracing head and shaftguide into said bearing housing.
